Definitions

  • the invention concerns a circular cooler for hot lumpy material, comprised of a ring-shaped frame supported on two circular rails by means of wheels and moving on these rails, bottom plates mounted to the frame and permeable to gas which fold down for the purpose of material discharge into track recesses, wind boxes located underneath the frame and the bottom plates to supply cooling air, and slide seals to seal the gap between the upper edges of the wind boxes and the bottom side of the frame.
  • Hot bulk material especially sinter ejected from sinter machines, for example, has to be cooled down before it is further transported, generally on rubber belt conveyors.
  • This is executed in part by circular coolers of the type described. With these circular coolers the gap between the upper edge of the stationary wind boxes and the bottom side of the rotating frame must be sealed as efficiently as possible; otherwise, a large volume of the cooling air will escape through this gap rather than being forced through the plates which are permeable to gas and onto the hot bulk material on these plates.
  • the invention is based on the concept of creating a simple sealing device permitting free movement of the cooler without affecting the sealing effect.
  • this problem is solved in that at the upper edge of the wind boxes or an extension of the upper edge of the wind boxes there are circular-shaped segments horizontally mounted with their outer edge, that the ring-shaped segments are designed to slightly bend upward and downward, that underneath the interior wall of each segment a sealing strip is attached, the sealing strips rest on a horizontal ring-shaped flange on the frame and that the weight of the sealing strips pulls down the segment against the existing overpressure on the bottom side of the section until the sealing strip is in contact with the flange.
  • the term "slightly bendable" means that the sections demonstrate a certain upward and downward flexibility, but are practically stable without any external influence. They might consist, for example, of adequate rubber material or thin sheet metal.
  • the required elasticity may also be obtained with rigid material which is attached to the upper edge of the wind boxes in an elastic mounting.
  • the sealing strips preferably should consist of steel sections or other wear resistant materials.
  • the sealing strip weight required to pull the segments downward may also be produced by applying weighted material, such as sheet metal strips, to the sealing strips or the segments.
  • a preferred design has the feature that the length of the ring-shaped segments is limited so that the tangent to the center of the inner circle, determined by the sealing strip, at the ends of the segments does not pass through the outer circle, determined by the upper edge of the wind boxes. Consequently, an especially effective sealing effect is obtained.
  • One preferred design has the feature that the sealing strips are in the shape of blocks.
  • the rectangular block design of the sealing strip produces an effective seal under any conditions, and wear and tear is relatively low.
  • FIG. 1 represents a schematic cross-section of the cooling trough
  • FIG. 2 shows a magnification of the seal
  • FIG. 3 is a top view of a section of the seal.
  • the ring-shaped frame 1 is supported on two circular rails 3 by means of wheels 2 and with the help of these wheels 2 runs on the tracks.
  • Located underneath the frame 1 are wind boxes 4 through which the cooling air is supplied and forced through the feed 5 resting on as permeable bottom plates 19.
  • Ring-shaped segments 8 are mounted horizontally with their outer edge connected to the extension 6 of the upper edge 7 of the wind boxes 4. Underneath the inner edge of segments 8 one sealing strips 9 each is attached.
  • a flange 10 is attached to the frame 1, sealing strips 9 are resting on the former.
  • metal sheet weights 11 are applied on top of the sealing strips 9 on segment 8.
  • An angle 12 at the extension 6 to which sealing strip 9 is attached allows the latter to be adjusted up or down.
  • FIG. 3 illustrates that the tangent 13 to the center of the inner circle 14 does not pass through the outer circle 15.
  • the distance of tangent 13 at the ends of segments 8 from the outer circle 15 can be chosen at random.
  • the contact points of the segments may be protected.
  • the advantages of the invention are that by means of a single seal an effective seal is obtained regardless of the movement of the cooler, the seal is not affected by dust, wear is relatively low, and the seal may be easily installed and repaired.
